PAPER-FILE SPECIFICATION forming part of Letters Patent No. 390,596, dated October 2. 1888.

Application tiled March 29, 1888.

To all whom may concern:

Be it known that I, LUDWIGr EDUARD HEIT- LING, a subject of the King of Prussia, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Paper-Fi1es, of which the following is a specification.

rlhis invention has for its object to provide a novel-paper-iile for binding, fastening, or holding letters, bills, journals. and the like, as set forth in the following specification and claims7 and illustrated in the accompanying drawings, in which- Figure lis a plan view of a tile. Fig. 2 is a vertical transverse section thereof. Figs. 3, 4, and 5 illustrate the operation of the file. Fig. 6 is a plan view of a rule which is useful in connection with t-he file. Fig. 7 is a transverse section of the rule.

Similar letters indicate corresponding parts.

In the drawings, the letters c b indicate two rails. To the rail b are secured flexible con nections d, such as cords, threads, or wires. The rail a has sockets h, serving as bearings for a shaft, c, having a handle, e, for rotating saidy shaf't and a shoulder or button,f, to prevent longitudinal displacement of said shaft c. A ratchet-wheel, g, adapted to be engaged by a stop or slide, i, on a socket, h, can be made to prevent rotation of the shaft c. The connections d pass from the rail b through openings in the rail a and are wound about the shaft c. By turning the shaft c in the proper direction the rails a b will be drawn toward one another or left free to be drawn farther away from one another, as required.

To bind articles such as letters or papers I proceed as follows: The papers to be bound are provided at one edge with incisions, the distances of which from each other correspond to the distances between the threads or wires d. The papers are then placed between the rails a b in such manner that the threads or wires pass into the incisions. After the paper has been placed in this position the shaft c is turned so as Vto draw the rails a b together with sufficient force to tightly clamp the papers between the rails. The slide or lock t' is then moved into engagement with the teeth of the ratchebwheel g, so that the rails are secured in position. Vhen other papers are to be added, the lock i is moved out of engagement with the wheel g and the shaft c is turned so as to allow the rail a to be moved tothe position shown in Fig. 3. The sheet to be bound is Serial No. 268,801. (No model.)

then placed upon the other papers which are already bound in such a manner that its edge is flush with the edges of the previously-bound papers. rIhe rail a, carrying the shaft c, is then moved to the position shown in Fig. 4, so as to cause the threads or wires to incise or out into the paper. The threads or wires are then wound up by turning the shaft c so as to press the rail a against the papers, as seen in Fig. 2.

In order to obtain uniform incisions by the threads into the several sheets, I employ a rule, j, Figs.6 and 7. This rule is provided with slits k, the distance between the slits corresponding to that between the threads or wires Au offset, Z, Fig. 7, enables the rule to be placed snugly against an edge of the package of papers bound. The ruleis placed upon the sheet to be bound, Fig. 3, so that the slits correspond to the threads. The rail a is then moved from the position shown in Fig. 3 to the position shown in Fig. 4, and the threads, passing into the slits k and into the sheet lying under the rule, make the incisions at the right place and in the direction given by the slits.

Vhat I claim as new, and desire to secure by Letters Patent, is-

l. A paper file combining in its structure vtwo rails, a and I), one movable to and from the other and provided with sockets l1, a shaft, c, revoluble in said sockets and movable with the rail to and from the other rail, and :threads or wires secured to one rail and connected with the shaft on the other rail to clamp papers between said rails, substantially as described.

2. The combination, with the rails a b and the threads or wires secured to one of said rails and wound upon the other rail, of a rule provided with slits corresponding in position to the position of the threads, substantially as described.

3. The combination, with the rails a b and the threads or wires secured to one of said rails and wound upon the other rail, of a rule provided with an offset, Z, and with slits corresponding in position to the position of the threads, substantially as described.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

LUDWIG EDUARD HEITLING.
